Description
Technical field
The utility model relates to a kind of electricity generating device.Specifically, be the ocean current power generation machine that has spoonful shape bucket that utilizes current (particularly ocean current) to generate electricity.
Background technique
As everyone knows, the surface of the earth is covered by large-area ocean, and under the promotion of wind-force and other power, seawater is following moving that certain route goes round and begins again all the year round, this has just formed ocean current, the scale of ocean current will be far longer than the river in the rivers and lakes of land, and it is a kind of inexhaustible, nexhaustible environmental protection resource.
In the last few years, in order to reduce the transition development and utilization of earth energy, countries in the world were all relatively paid attention to utilizing the environmental protection resource to generate electricity, and this wherein just comprises ocean current power generation.Traditional ocean current power generation machine comprises water turbine and generator, and the rotating shaft of water turbine links to each other with the input shaft of generator, and whole ocean current power generation machine need be fixed on the seabed by column and transverse arm.During operation, promote the water turbine rotation by ocean current, drive generator work by water turbine again, thereby generate electricity.Though utilize this ocean current power generation machine to generate electricity, because the flow velocity of ocean current is slower, below 1 meter per second, specific power is little usually, wants to improve the generated energy of unit, just must do the blade of water turbine very big.Like this, the column that is used for supporting the ocean current power generation machine is also thick, and in the seabed column is set, and must after the piling of seabed column could be installed earlier, and this just makes the difficulty of construction increase, the manufacture cost rising.And, owing to be subjected to the influence of marine ecosystems and the restriction of water turbine intensity, the blade dimensions of water turbine can not unconfinedly increase, even if with its size do very big, also the entrained kinetic energy of ocean current 1 meter per second flow velocity simply can only be changed, thereby the generation electric energy, this generated energy is very limited, can't realize powerful requirement.
The model utility content
Problem to be solved in the utility model provides a kind of with spoonful power station using ocean currents of shape bucket.This electricity generating device is installed in the ocean current power generation system, not only can reduces manufacture cost, and its generated energy is higher, can reach powerful requirement.
For addressing the above problem, take following technological scheme:
The characteristics of the power station using ocean currents of band spoon shape bucket of the present utility model are to comprise conflux pipeline, water turbine pipeline and wake flow pipeline, conflux pipeline and wake flow pipeline are bucket-shaped, the less end of their bores is connected respectively at the two ends of water turbine pipeline, the end that the conflux pipe diameter is bigger is the ocean current entrance, and the end that the wake flow pipe diameter is bigger is the wake flow outlet.On the described water turbine pipeline water turbine and generator are arranged, link to each other by gearbox between the input shaft of generator and the rotating shaft of water turbine.Described water turbine contains the cylindrical case of lateral arrangement, and this cylindrical case is closed shape, and rotating shaft is positioned on the axis of cylindrical case, and the rotating shaft upper edge circumferentially is evenly equipped with many row's spoon shape buckets, and every row's spoon shape bucket is all along the rotating shaft axial arranging.The downside of described cylindrical case is processed with the opening that connects its length, on the water turbine pipeline upper wall opening is arranged, be around the opening of cylindrical case and between around the opening of water turbine pipeline and be sealedly and fixedly connected, make spoon shape bucket stretch in the water turbine pipeline by this opening and make the rotating shaft of water turbine and water turbine pipeline vertically perpendicular.
The further improvement of the utility model scheme is that described water turbine has two at least, and they are vertically arranged along the water turbine pipeline.Adopt the mode of multistage water turbine series connection, can carry out recycling to the ocean current wake flow after the acting, make it again to the water turbine acting of back one-level, the kinetic energy that it is entrained further is converted into electric energy, thereby realizes taking full advantage of of ocean current kinetic energy.
The further improvement of the utility model scheme is that described water turbine pipeline has two at least, and their end is side by side that shape is connected the less end of conflux pipe diameter, and their the other end all is connected with the wake flow pipeline.All be connected with water turbine on described at least two water turbine pipelines.Many water turbine pipeline arranges, can further dwindle the cross-section area in each water turbine pipeline, reduce the generation of sinuous flow phenomenon, and can only between water turbine corresponding on adjacent two water turbine pipelines, connect a generator, thereby make this electricity generating device center line bilateral symmetry longitudinally, guarantee the balance of device.
The further improvement of the utility model scheme is that the end that described water turbine pipeline is connected with the conflux pipeline is provided with valve, on this valve hydraulic pressure installation is arranged, by the folding of this hydraulic pressure installation controllable valve door.Utilize this valve control to enter the interior ocean current of water turbine pipeline, can control the keying of generator, the generator idle running when avoiding the no-output state, thereby the working life of increase generator.
The ocean current entry end that further improvement project of the present utility model is described conflux pipeline has filter screen.Can tackle marine organisms or other material enters in the conflux pipeline by this filter screen, thereby avoid obstruction or the damage of water turbine pipeline, when not influencing marine ecosystems, increase the working life of device.
Take such scheme, have the following advantages:
Because the conflux pipeline of the power station using ocean currents of band spoon shape bucket of the present utility model is bucket-shaped, the bore of its ocean current entry end is greater than the other end, therefore, after ocean current enters the conflux pipeline, its flow section constantly dwindles, the potential energy converting and energy that the huge static pressure of ocean current self that namely utilizes funnelling will enter this pipeline has becomes the kinetic energy of ocean current, thereby increases the flow velocity of ocean current, has promoted the specific power of ocean current kinetic energy greatly.If the cross sectional area of ocean current ingress is 10 times of conflux pipeline and water turbine pipeline connecting end cross sectional area, ocean current is in flow process so, its flowing velocity will increase to original 10 times, because specific power is directly proportional with the cube of speed, be that specific power increases to original 1000 times, narrow down at area under one of 1/10 the situation that total output increases to 100 times of ocean current ingress, thereby improved the generated energy of device greatly, it can satisfy powerful designing requirement.Meanwhile, utilize the mode that increases the ocean current flow velocity to improve generated energy, can dwindle turbine size, and then dwindle the volume of electricity generating device integral body, thereby can reduce manufacture cost greatly.
